osprober complaining about ZFS is a known issue. I don’t know if I bothered to file a bug report, so this will probably be the report for that.

I tried the daily yesterday but I had no ZFS option. ** Changed in: zfs-linux (Ubuntu) Status: New => Confirmed ** Summary changed: - Error during update ZFS installation and during update-grub + osprober prints errors about ZFS partitions -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1847632 Title: osprober prints errors about ZFS partitions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1847632/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
